1. CLAUDE.md and README.md described the superseded Python service. Both now
describe server/ (Go), say plainly that the Python files at that level are
the original the port was made from, and drop CLAUDE.md's claim that
`make test-unit` is "the tier CI runs" — CI's only frontend check is the
Dockerfile builder stage's gofmt + vet + go test.
2. static/units.js's F_REGIONS was guarded by nothing, despite three source
comments claiming "a test asserts all three stay identical": the only check
compared the Go set against the backend's Python. TestFCountriesMatchesUnitsJS
now diffs the browser copy both directions.
That backend cross-check also skips in CI — the image build context is
frontend/, so backend/ is unreachable from the builder stage, which is the
only place CI runs these tests. static/ IS in the context, so the Dockerfile
copies units.js into the builder and the new assertion runs during the image
build. Verified by mutating units.js and confirming the build fails.
3. Both docker-compose.test.yml files defaulted to the retired
emi/thermograph-backend/app path, and the frontend harness pinned the
split-era v0.0.2-split-ci tag. Path corrected in both. Rather than swap one
hardcoded pin for another, backend-for-tests.sh now derives the tag from the
checkout — sha-<12hex of `git log -1 -- backend/`>, the same domain-keyed
rule build-push.yml and deploy.yml use — and compose requires the variable
so a stale pin cannot creep back in.
Verified: backend 429 passed/8 skipped; frontend go vet clean and all packages
ok; frontend image builds; `make backend-up` pulls and serves on the derived
tag; shellcheck zero findings across the tree.
Unrelated pre-existing issue noted in the docs, not fixed here:
`make test-integration` fails 7/16 with 503 against a cold throwaway backend
(empty database, nothing warm). Reproduced identically on the old image, so it
predates this change.
